All files on both hosts or just some specific links? Are you copying the complete link or missing a part?
And finally, are you opening them one by one or parsing into an external program or are you doing something else.
Please try to add as much information as possible so things can be figured out faster.
Since I'm on my phone connection, I can't do any extensive debugging. If your description of the problem and used methods is detailed enough there's a fair chance I'll figure it out from here. If not, you'll have to wait till I get home.
